Situation. Situation. Situation.?

Been talking to a boy over facebook, texting. Then we starting talking over phonecalls. It had been going on for about a week, then we met up in a club in town for the first time. He was abit of an idiot, wasn't really speaking to me much, and all I could think to myself was this isn't the lad I was speaking to on the phone. Anyway, I found out later on he had been smoking weed and was stoned, which was nice to know as I have never touched even one cigarette in my life. Later on, we met up in another club and he didn't really make the effort to speak to me, so I rang him up and he said he was outside. So off I went outside and we just kissed. But I thought we were just friends before this, I was extremely drunk and he was too. Don't know if it meant anything. But he said I was beautiful and was showing me his phone, saying look we have text nearly 800 times in the space of a week. So we were kissing outside and then we walked off down the street and he threw up. I spent over two hours with him whilst he threw up, I was helping him. Then finally later on he got in a taxi, think he appriciated the fact I wasted most of my night with him whilst he was being sick. But when I think about it, I'm glad I was there helping him and not someone else. But tbh, I don't know. Then after that night, It has been two days and he seems like he doesn't want to speak to me for some odd reason. I feel like he is avoiding me, and trying to not talk to me. I feel like I'm the one who is trying, who is talking first and making the effort. In all honesty, I know we have only known each other for over a week, but I can see something there. I just don't know. But the thing is, I don't want to ask him if he feels anything for me as he might just think of me as a friend, and then it will most probably make our friendship awkward and that will be the end of it. I don't want to be the one who texts him first or chats to him over facebook first, or asks him when are you next out round town? He sounds like such a bad guy with all the weed and stuff, but he doesn't usually do it. It is very rare that he does, he isn't a bad guy, so I just want to know what to do about the situation of talking to him. So please don't tell me to stay away from him because he smokes weed and everything. Mainly, what should I do. Wait for him to text me? Even if it does end up being 10 at night, or not even that night but a few days. Should I make him chase me? And if so .. How? How do I make him what to know me more or want to see me again? Please help :( I don't like looking like I'm desperate by texting or talking to him first. A BIG thank you to people who reply. Xx
